摘要
在矿井开采初期，并巷围岩的位移是矿井支护的重要指标．本文利用已知观测数据结合时间序列分析中的逆函数法来预测开巷初期的围岩位移量．同时对数据的预处理进行了探讨．以满足动态数据的等时性及平称性要求．
Displacement of surrounding rock is an important target on tunnel support. In this paper,converse function method in time series analysis, with measured data, is used to forecast displacements of surrounding rock at the initial tunnel opening. To satisfy the needs of dynamic data'sisochronism and stability,the pretreatmept of data is researched.
